ALLENTOWN, Pa. - The Academy of Motion Picture Arts and Sciences says it's not in the business of vetting best documentary contenders for truth and accuracy.

That's up to Oscar voters.

The academy has responded to attacks on the documentary "Gasland," a critical look at natural gas drilling.

An industry group named Energy In Depth questions the film's truthfulness and has asked the academy to reconsider its Oscar eligibility.

Bruce Davis is the academy's executive director. He said in a letter to Energy in Depth that the academy doesn't have the resources to investigate each nominated film. He says Oscar voters can be trusted to sniff out distortions and half-truths.
